Is any one running TopsXtreme software? What I would like to know is if you are having any problems with it. We are running a Dual G5 1.8. We started off with system 10.3 and have reformatted the drive and installed 10.4. We have just had the logic board and the ram replaced. There is no software on this computer other than 10.4 and updates, TopXtreme V2.1, and customers data. What is happening is the the computer is locking up, to such an extent that the fans are running full speed and the only way to do any thing is to push the power button until the computer shuts down. This is common to both OSs. Any ideas really would be appreciated. Bob
